I16"; I11;

decreased by turninga screwlocated the 5-5 sidewall portions I-6",-II"are relievedattheir rear-boundariesbytheslots I 8, I9; which areabout 'si-x inches long' and extend for equal dis}- tances above and"below the countersunk" hole which is substantially at the height of themeeting rail of the sashes 2 I, 22.

Referring to Figure 2, in which sash 2!, 22 have been omitted, a runner23 is slidably mounted in channel l2 and a similar runner 24 is slidablymounted in channel l3. Runners 23, 24 have integral flanges 25, 26 whichare bent so as to form a U shape with the body of the runher, as bestshown in Figure 4.

Runner 23 'is further formed with the pivot hole 21 and the arcuate slot28.

The tilters 29, 30 are metal members of L cross section, a pair oftilters on opposite sides of the window constituting mounting means fora sash 2| or 22, which are preferably permanently mounted in the pair oftilters by screws or other conventional means.

Tilter 29 is formed with the pivot hole 3i and the square hole 32 ata-substantial distance there from.

The bolt 33 has a square shank portion 34 which fits vnonrotatably inhole 32 and rides in the slot 26 when tilter 29 is tilted on pivot 35.

Inside of runner 23 and on the opposite side thereof from tilter 29 isfirmly mounted, as by welding, the friction plate 36 formed with thearcuate slot 31 coincident with slot 28.

Washers 38, 39, 40 are mounted on bolt 33 between tilter and runner,runner and friction plate, and friction plate and nut 4| respectively,

washers 38, 39, 46 being formed with holes complementary to the squareshank portion 34 so as to be nonrotatable thereon. It is evident fromthe above that bolt 33 also extends through slot 31 of friction plate 36and that nut 4| threadedly engages bolt 33.

The above described mechanism constitutes a tilt lock which byadjustment of nut 4| on bolt 33 by insertion of a wrench into the lowerend of runner 23 as indicated by arrow 42 permits the development of anydesired degree of sliding friction between tilter 29 and runner 23 sothatv the tilter can maintain any angular position to which it is setrelative to runner 23. 7

Screw 43 passes through countersunk hole 26 in face portion I5 ofparting strip [4. Compression coil spring 44 is mounted concentricallyon screw 43 between face portion I5 and tapered, elongated nut 45 whichis threadedly engaged by screw 43.

Nut 45 engages the side wall portions l6, I! to distend the samelaterally when screw 43 is taken up, thus creating frictional engagementbetween portions I6, I! and the runners 23, 24 of both upper and lowersash, thus providing easy adjustment of the sliding friction betweenrunners and stile ll so that the runners maintain any vertical positionto which they may be set.

The flanges 25, 26 overlie the upper extremities of the tilters when thelatter are in closed position, as illustrated re tilter 36, Figures 2and 4,

while an open position of tilter 29 is also illustrated in Figure 2. 7

Means for floatingly mounting the. stiles H in the window frame 10 areprovided in the tongues 46 struck out of the material of II, one tongue46 being located about one foot from the end of each channel l2, l3.Tongues. 46 are integral with stile l I, being connected thereto, at

their upper end, and free standing along their side and bottomboundaries. A nail or screw driventhrough each tongue 46 into the.conventional pulley stile serves to mount the stiles II in the frame I0and guards against poor sliding of the sash due to compressive deformingof frame In by settling of the wall which may cause 7 the opening to getout of square. Slight settling of the window opening is enough to deforma frame I0 conventionally mounted therein, but the present inventionpermits stile II to maintain its correct relation to the sash, thuspermitting normal functioning of the window.

It will thus be seen that there is provided a device in which theseVeraIobjects of this invention are achieved, and which 'is well adapted tomeet the conditions of practical use. As various possible embodimentsmight be made of the above invention, and as various changes might bemade in the embodiments above set forth, it is to be 7 understood thatall matter herein set forth or shown in the accompanying drawing is tobe interpreted as illustrative and not in a limiting sense.

What is claimed is:

1. In a window construction of the type comprising slidable and tiltablesash, a runner member slidable in the window stile, a tilter memberconstituting mountingmeans for said sash and a pivot connecting saidtilter to said runner, the

improvement comprising said runner member being formed with a slot, saidslot describing a segment of a circle around the center of said pivot,and said tilter member being formed with a hole, a bolt passing throughsaid slot and hole and a nut engaging said bolt and thereby drawing saidtilter and runner into frictional engagement to constitute a tilt lock.7

2; Tilt lock means for tiltable and slidable sash comprising thecombination with a tilter member firmly connected to said sash, a runnermember slidably engaging thewindow frame, and a pivot connecting saidmembers, of a third member firmly mounted on said runner member on theopposite side thereof from said tilter member, said tilter member beingformed with a hole, said runner and third members being formed withslots, said slots describing a seg-. ment of a circle around the centerof said pivot, a bolt passing through said hole and said slots, and anut on said bolt in back of said third member.

3. Tilt lock means, for a tiltable and slidable sash comprising thecombination with a tilter member firmly connected to saidsash, a runnermember, slidably engaging the window frame and a pivot connecting saidmembers, of a third member firmly mounted on said runner member on theopposite side thereof from said tilter member, said tilter member beingformed with a hole, said runner andthird membersbeing formed with slots,said slots describing a segment of a circle around the center of saidpivot, a bolt passing through said hole and said slots, a nut on saidbolt in back of said third member, and washers on said bolt between saidtilter and said runner member and between said runner and third memberand between said third member and said nut.

4. In a tilt lock means according to claim 3, said bolt comprising aportion of noncircular cross section and said washers being shapedcomplementary to said portion.

5. Tilt lock means for a window with slidable and tiltable sash, saidmeans comprising, in combination, a tilter member firmly connected tosa1d sash, a runner member of U-cross section,

the bight' of the U abuttingsaid tilter member and the arms of the Uslidably engaging the winon the bight of said runner member adjacent thelower end thereof and on the opposite side thereof from said tiltermember, said tilter member being formed adjacent its lower end with ahole for a pivot, said runner and said third members being formed withslots, said slots describing a segment of a circle around the center ofsaid pivot, a bolt passing through said hole and said slots, a nut onsaid bolt in back of said third member, and washers on said bolt betweensaid tilter and said runner members, and between said runner and saidthird members and between said third member and said nut, said nut beingaccessible for adjustment via the open lower end of said runner member.
